And with the arrival of my undercarriage parts and rubber tracks, I can finalize the design of the loader and get to building...

I needed to finish up a pesky little thesis before getting back to the loader project, but now I'm ready to go.

I measured the tracks, rollers, and drive gears and with that information designed the undercarriage layout. I will be manufacturing the idler/tensioner wheels fore and aft in the undercarriage assembly myself rather than buying them. Next I need to design some retainer plates for the undercarriage and then start ordering steel and cutting. I updated the track drive design too. I think I am going to go back to 1:1 drive on the motor/drive shaft connection since I probably don't need a top speed of 9 mph on this thing and would like the additional torque for pushing/pulling power.

I've been trying to finish a tile floor in the basement so I can my shop set up down there and move some stuff out of the way in the garage. I did buy all my hydraulics though (except lines since I want to bolt everything down and measure before getting those). I'm hoping to finish the floor and set my basement shop up this weekend so I can get to cutting and welding after that. More to come soon...

Hi Zack, tracks look like they dig in really good. If you don't mind me asking, where did you get them?

Back to work a bit on the track loader...

I built my drive axles, installed my "transmission cases" and started welding those in place. I welded the engine mounts in place and welded the hydraulic pump mount to the rear engine mount. Next I'll finish welding in the transmission cases then I need to buy some more plate and box beam to cut out the undercarriage frames. I'll keep plugging away little by little. Maybe I'll have a track loader in another few years....

So I ended up moving to a new place and took quite some time to move my shop, get set up and get back to work. But I bought my rectangular tubing, set up my shop and am finally back to work. I cut most of my tubing with the bandsaw and have been working on dialing in my little CNC plasma machine. I also have the idler and tensioner wheels in work. I'm facing down some large cast iron/rubber wheels rather than welding up from scratch. Lots of stuff in work, slow progress, but its better than no progress. At this point I'm thinking this little project is going to wrap up sometime around 2018... crazy . I'll try to add some pictures the the main slide show section.

Sounds great!
I can relate to the time thing.... crazy
Pictures would be awesome, sounds like you're doing well.
Is the new shop bigger than the last one?

I added some picture to the main posting. the new shop is a 2-car garage plus a small storage room for hardware, parts and tools I'm not using at the time, which is a step up from the small 1-car garage and basement combo at the old place.

So I forgot to weld on the pin bushings to the quick attach assembly...oops. So I did that tonight after I finished the first piece of the ROPS today. I built one vertical post which will hold the boom lift cylinder on the lower set of mounting ears and the boom itself on the upper set. I'm finally starting to weld some decent welds. This project is my opportunity to teach myself to weld. I've noticed quite a difference since I started on it to now. I still would not consider myself a really good welder, but I think I'm making solid structural welds even if they are ugly a lot of the time. Added some more pictures to the main posting again.

I've been welding away on this project slowly making progress. I assembled the canopy components and am now ready to weld those to the chassis. I put a bit too much heat into welding the ears on and they stress relieved by bending inward (that's why I have some bolts in them trying to pry them back open). I may have to heat them and carefully bend them back open, but that's for another day. I assembled one side of the boom and now just need to weld the lower leg in place. Then time to start the second arm of the boom. It seems to slowly be getting closer. Probably won't be shoveling the driveway with the little loader this Winter, but we'll see. I added more pictures to the main gallery post again.

Did some more work today. A friend of mine stopped by and helped me get the roll cage welded in place. I got it generally attached and then put the old engine crane back together and tipped the whole body over on its side so I can weld up all the joints in a flat orientation. I'll clean up the bottom of the machine while I have it tipped over. It was an interesting process tipping it, so I'm sure it will be fun getting it flipped back over so I can weld the opposite joints. But after this I think the body is mostly complete and ready for final grinding, smoothing, prepping and painting.

Sounds like you're making good progress.
Not sure about others here, but I can't see any of the latest pictures you've posted.

I added them to the top post / gallery images...i can see them when i look at the member gallery section. If that you don't see them up there, let me know and I'll try to find a way to re-post somewhere else. I try to work at least part of a day per week now...still holding onto a bit of a dream that I might plow the driveway if we get a big snow this Winte, but I don't think I'm actually that close yet. Thanks for keeping an eye on my progress

The last picture I can see is the finished axle.
After that there appears to be roughly 30 more that don't show up for some reason. Clicking on it, the description shows but not the picture. frown
